The improvement of insulin resistance and the antioxidant capacity in type 2 diabetes mellitus rats with whiteleg shrimp shell powder (Litopenaeus vannamei)

Anotace: As estimated having an increased incidence of about 50% until 2040, the diabetic condition could be augmented primarily from astaxanthin contained in carotenoids. This research examines and compares the influence of WSSP and AST complement on Homeostatic Model Assessment-Insulin Resistance (HOMA-IR) level and Total Antioxidant Capacity (TAC) induced high-fat diet streptozotocin (HFD-STZ) in T2DM rats. WSSP 0.89gr/200gr/d (X1) and 1.77gr/200gr/d (X2) groups; and AST supplement 0.09mg/200gr/d (X3) groups were compared with both of positive (K1) and negative (K2) groups. The treatments were administered orally for 21 days to 25 Wistar rats which each group consisted of 5 rats. HOMA-IR and TAC levels were measured by ELISA and ABTs method respectively. TAC levels significantly increased in treatment groups than K1 group (p = 0.008). The increase in the TAC level of the X2 group was greater than the X1 group (p = 0.017). HOMA IR levels were significantly lower in treatment groups than K1 group (p = 0.009). X2 group had a greater decrease in HOMA IR levels compared to X1 (p = 0.016). In consequence, the research findings show a utilitarian effect of WSSP in increasing TAC and decreasing the HOMA-IR index.
